中国科学家发表研究，揭示美国和中国女性阴道微生物组的差异，一种与细菌性阴道病和早产相关的细菌在美国女性中更普遍且毒性更强。
这项研究于6月11日发表在《自然遗传学》期刊上。研究人员自2018年开始收集样本，绘制出全球最广泛的女性生殖道基因组图谱。
研究强调需要针对本地化的医疗治疗，而非基于西方人群数据的标准化护理。研究人员表示，这填补了亚洲人群的关键空白。
参与机构包括华大基因研究院、南方科技大学、北京协和医院、北京生命科学研究所和复旦大学。

Researchers at APC Microbiome Ireland at University College Cork report that early-life exposure to a high-fat, high-sugar diet altered feeding behavior and appetite-related brain pathways in mice into adulthood, even after the animals returned to a standard diet and normal body weight. The team also found that a specific Bifidobacterium strain and a prebiotic fiber mix helped mitigate some of these long-term effects.
Gut bacteria that recycle oestrogens back into the bloodstream are far more abundant in people from industrialised societies than in hunter-gatherers and rural farmers, according to a new study. Researchers found up to seven times greater recycling capacity in urban populations. The findings raise questions about potential health impacts from elevated hormone levels.

Researchers have uncovered links between microbes in the mouth and metabolic conditions like obesity, pre-diabetes, and fatty liver disease. The study analyzed oral swabs from over 9,000 participants using advanced sequencing techniques. Experts suggest these findings could lead to simple swab-based screenings.
